Best Airline for Flying with an Infant (2026)

Fees, policies, and figures in this guide reflect what we verified as of Oct 2026 and can change afterward. Our live tools and the data behind them are re-verified more often than the written guide.

Flying with an infant in 2026 is more complicated than it should be for two reasons: the DOT family-seating rule that would have required free same-row assignment for kids 13 and under stalled when administrations changed in January 2025, and Southwest’s transition to assigned seating in early 2026 ended the open-seating pre-boarding strategy that families used for decades to find seats together. That makes seat assignment matter as much as the bassinet specs most guides focus on.

The bassinet specs do matter though, especially on long-haul. The best airline for flying with an infant in 2026 depends on the age of the baby, the route, and whether you’re willing to pay for a separate seat instead of using lap-child status.

The best long-haul newborn pick is Lufthansa or Air France: Lufthansa puts bassinets across its long-haul fleet, and Air France offers them on long-haul flights, subject to availability and aircraft configuration. The best crawler-to-toddler pick (6-18 months) is Singapore Airlines, whose 14 kg (31 lb) bassinet cap is the highest any airline here publishes, fitting older babies that bust the 20-25 lb caps on competitors (Economy and Premium Economy only). The best premium cabin pick is Qatar Qsuites. Planning on Delta One? Delta offers free SkyCots in select seats on equipped widebody aircraft but does not say which cabins, so ask Delta before you book. For US domestic, JetBlue and Southwest are the friendliest, though Southwest’s 2026 assigned-seating change has weakened the historical pre-boarding advantage.

Avoid Allegiant and Frontier for long international travel with an infant because neither operates widebody aircraft, so neither offers bassinets.

Update (May 2026): Spirit Airlines stopped flying for good on May 2, 2026, when its second Chapter 11 converted to a Chapter 7 liquidation, so it is no longer a carrier you can book at all. We have left its historical row in the comparison below, but families who used to fly Spirit on a budget should now look at Frontier, Allegiant, or Breeze for domestic hops.

Side-by-side airline comparison (2026)

Every carrier in the table accepts lap children under 2 years old, and strollers and car seats check free on every major airline, so the table below leaves those out to make the meaningful differences readable. Whether a diaper bag counts as your personal item depends on the airline, so check its carry-on rules (links at the end).

What we looked for

• Bassinet availability per cabin, since the most-corrected family-travel myth is that all premium cabins have bassinets
• Weight cap on bassinets, where Singapore (14 kg) leads, most published caps fall between 9 and 11.3 kg, and United publishes no cap at all
• Lap-child fees on international flights, where 10% is standard and Air Canada charges a flat $25 CAD / 2,500 Aeroplan points per direction on award tickets
• Stroller and car-seat policies, all carriers free but enforcement varies
• TSA rules around baby formula and breast milk, all exempt from 3-1-1 but separate screening required
• Family-seating commitments, where the DOT dashboard tracks which US airlines guarantee free family seating (section 7)

1. Lufthansa and Air France (the long-haul newborn winners)

For long-haul flights with a newborn (under 6 months), Lufthansa and Air France are the structural picks.

Lufthansa. Bassinets across the entire long-haul fleet, for babies up to 8 months. 11 kg / 24 lb weight cap. 67 cm internal length. Lufthansa’s baby page does not list cabins, but its Allegris Business Class page says the Privacy Seat in the last row can be fitted with a bassinet. Lufthansa is widely cited in r/parenting and Mumsnet as the European long-haul default for families.

Air France. Bassinets on long-haul flights, subject to availability and aircraft configuration, for infants under 10 kg (22 lb) and 70 cm. We have not confirmed which cabins carry them, so confirm a bassinet position in your cabin when you book, especially in Business, where a bassinet plus a lie-flat seat is the most workable combination for parents who need to sleep while the baby sleeps.

Both carriers. Free stroller check, free car seat check. 10% lap-child fee on international tickets. Crew culture is reportedly attentive to infants based on FlyerTalk and Mumsnet threads.

2. United Airlines (widebody bassinets, no published weight cap)

United offers free bassinets on request in Polaris business class and on select international Economy flights, subject to limited supply, and they can only be used while the seatbelt sign is off.

United does not publish a bassinet weight limit. That matters most for 6-18 month-olds. An 8-month-old is often around 22 lb (the median weight for that age), which is already at Air France’s 10 kg (22 lb) cap and over Alaska’s 9 kg (20 lb), so call United and confirm before you plan around a bassinet. If you need a published cap that fits an older baby, Singapore Airlines is the highest at 14 kg (31 lb), in Economy and Premium Economy only.

Bassinet positions differ by aircraft and cabin layout, so check the seat map for your flight when you book, and ask United to confirm when you request the bassinet.

3. ANA and JAL (the transpacific picks)

For flights to or from Japan, Korea, or anywhere in Asia, ANA and JAL are the structural picks.

ANA. Bassinets on all international aircraft for infants up to 10 kg (22 lb), but not in First Class. ANA’s own 787-9 seat map lists bassinet seats in Business Class as well as Premium Economy and Economy, so check the seat map for your aircraft and reserve 48 hours ahead. Cultural patience with kids is widely reported across FlyerTalk and Reddit. Infant meals are bookable in advance. The new “The Room” business class on the 777-300ER (now widely deployed) accommodates parents with an infant in lap or in a side-by-side configuration.

JAL. Bassinets on all routes except JTA international flights, for infants up to 10.5 kg / 23 lb, and you must reserve one in advance. JAL does not say which cabins carry them, so ask when you reserve. JAL stocks diapers on board, a unique amenity among major carriers.

Both ANA and JAL are widely praised in Reddit r/JapanTravelTips and r/parenting for flying with infants. Cultural patience with crying babies is reportedly meaningfully higher than US legacy carriers.

4. Delta One and bassinets (ask before you book)

Delta One’s lie-flat suites look like the natural pick for a long flight with a baby. Delta does not say whether you can get a bassinet in one.

What Delta publishes. Free SkyCot bassinets for children under 25 lb (11.3 kg) and up to 26 inches (66 cm) long, on widebody international flights or widebody domestic flights over 1,500 miles, in select seats on equipped aircraft. SkyCots are limited to two per aircraft, and final confirmation happens at the gate. Delta’s infant-travel page never says which cabins those seats are in. Neither does its travel-agent seating guide, which covers SkyCots under bulkhead seating and mentions Comfort+ and Preferred seats, but not Delta One.

What to do. Before booking Delta One with an infant, ask Delta Reservations whether your flight has a SkyCot position in that cabin, and request the SkyCot on the same call. If it does not, the lie-flat seat still works for lap sleeping (one FlyerTalk reviewer, “acrophobia,” called it “vastly more comfortable sharing a D1 seat with an infant than a Y seat”), but it is not the same as having a bassinet during sleep periods. On a 10+ hour flight, a seat with a confirmed SkyCot can matter more than the lie-flat bed.

American Flagship Business has none (American says so for First and Business), and neither do Singapore Suites and Business. Emirates, United, Lufthansa and ANA publish premium-cabin bassinets; ask Qatar, BA and JAL which cabins.

5. Qatar Qsuites and Emirates Business (the premium cabin sweet spots)

For premium cabin travel with an infant, Qatar Qsuites are the consensus best product.

Qatar Qsuites. In a Qsuite Quad, movable panels turn the space into a double bed, so two adults plus an infant can share an enclosed sleeping area. Qatar provides bassinets for infants up to 11 kg / 24 lb and 24 months, but not in First Class on the A380, and it asks you to contact it to confirm a bassinet position on your aircraft and cabin. Cabin crew help with infant feeding is widely praised.

Emirates Business and First. Emirates offers bassinets in Business and First as well as Economy and Premium Economy, for babies up to two years old and 11 kg (24.3 lb). The First Class bassinet is smaller, 63.5 cm (25 in) long against 75 cm (29.5 in) in Business and Economy, so it suits younger babies. Request one in advance.

Best business class with infant overall: Qatar Qsuites if you can get a Qsuite Quad and Qatar confirms a bassinet position, Emirates Business, ANA Business on a 787-9 bassinet seat, or Lufthansa’s last-row Allegris Business Privacy Seat. Avoid American Flagship Business and Singapore Suites, and ask Delta before booking Delta One.

6. Lap-child fees and Air Canada’s flat award fee

Standard international lap-child pricing is 10 percent of the adult base fare plus taxes. Most carriers follow this convention.

Air Canada is the exception worth knowing. On award tickets specifically, lap infants fly free within Canada and between Canada and the US, and cost just $25 CAD or 2,500 Aeroplan points per direction on every other route (plus applicable taxes). For a family using Aeroplan points to book a long-haul Business Class award, the infant cost is essentially negligible.

British Airways award fees. 10 percent of revenue fare or 10 percent of Avios on award tickets. More expensive than Air Canada but still better than carriers that charge full taxes plus fees.

Southwest. Free lap children on domestic. International (Caribbean, Mexico) varies but generally free with taxes only.

JetBlue. Taxes only on most international routes. Effectively free except for fees.

Frontier, Allegiant. Free or taxes-only on their limited international networks. (Spirit had the same taxes-only approach but ceased operations on May 2, 2026.)

7. The 2025-2026 family-seating news

The DOT’s August 2024 Notice of Proposed Rulemaking for family seating (which would have required carriers to seat kids 13 and under next to an adult for free within 48 hours of booking) stalled when administrations changed in January 2025. The rule has not been finalized.

5 of 9 US airlines on the DOT Airline Family Seating Dashboard guarantee free family seating (checked October 2026):

• Alaska Airlines, American Airlines, Frontier Airlines, Hawaiian Airlines, JetBlue: yes
• Allegiant Air, Delta Air Lines, Southwest Airlines, United Airlines: no formal guarantee

Practical implication for 2026 booking: book seats together at the time of ticket purchase, even on Basic Economy fares where seat selection costs extra. The fee for advance seat selection is meaningfully less than the stress of a gate-side reseating with an infant.

8. TSA rules and what you can carry

TSA-confirmed 2026: baby formula, breast milk, toddler drinks, puree pouches, and ice/freezer packs are all exempt from the 3-1-1 liquid rule. Reasonable quantities are permitted through security. Breast milk is transportable without the child present.

You may be asked to remove these items from your carry-on for separate screening. Plan for some extra time at security, since screening varies by time of day and checkpoint.

Strollers and car seats are checked at the gate (stroller) or at the bag drop counter (car seat). They don’t go through the security checkpoint with you typically.

A diaper bag may count as your personal item rather than an extra bag. Check your airline’s carry-on rules before you pack.

9. Worst airlines for flying with an infant

For long-haul international:

• Allegiant, Frontier: zero widebody fleet, zero bassinets ever (Spirit shared this limitation but ceased operations on May 2, 2026 and no longer flies)
• Delta One, unconfirmed: Delta does not say which cabins get SkyCots. If Reservations cannot confirm one in Delta One on your flight, book a seat that can take a SkyCot instead.

For US domestic:

• The remaining budget carriers (Frontier, Allegiant) are workable for short domestic flights with a lap child but bring backup entertainment because no in-flight entertainment is included. (Spirit, once part of this group, ceased operations in May 2026.)

For 2026 booking specifically:

• Southwest under new assigned seating has weakened the historical pre-boarding strategy.

The bottom line

For long-haul flights with a newborn (under 6 months), Lufthansa or Air France are the structural picks. Lufthansa offers bassinets across its long-haul fleet; Air France offers them on long-haul flights, subject to availability and aircraft configuration.

For crawlers and older infants (6-12 months) that outgrow the 9-11.3 kg caps most airlines here publish, Singapore Airlines’ 14 kg (31 lb) bassinet is the highest published cap, in Economy and Premium Economy. United has widebody bassinets but publishes no weight limit, so confirm with the airline first.

For transpacific (Japan, Korea, Singapore), ANA or JAL are the structural picks. Both offer bassinets on international flights, both have infant meals, and JAL uniquely stocks diapers on board.

For premium cabin travel with an infant, Qatar Qsuites are the consensus best, once Qatar confirms a bassinet position in your cabin. Emirates Business, which has published bassinet sizes, is the second-best. Avoid American Flagship Business and Singapore Suites, which have no bassinets, and ask Delta before booking Delta One, since Delta does not say which cabins get SkyCots.

For US domestic, JetBlue is the easiest (priority boarding regardless of age) and Southwest is still workable despite the 2026 assigned-seating change.

Avoid Allegiant and Frontier for long international with an infant because neither operates widebody bassinets. Spirit, which had the same no-widebody limitation, ceased operations in May 2026 and is no longer bookable. Alaska, by contrast, does offer bassinets on many A330 and 787 flights, up to 20 lb (9 kg), if you buy a Premium Class seat in row 14.

For airline-specific carry-on and personal-item rules that matter when packing a diaper bag, see the JetBlue carry-on guide, Delta carry-on guide, Lufthansa carry-on guide, and Air France carry-on guide. For comparison head-to-heads, see JetBlue vs Delta, Air France vs Lufthansa, and ANA vs JAL.
